Siemens Healthineers has identified an issue with the RAPIDPoint500e system software version 5.3. This issue affects how the sample source is identified at the LIS when using the capillary mode. With this software version, samples run in the capillary mode are incorrectly labeled as arterial when displayed on the LIS, leading to the potential for results to be flagged according to an established arterial range. Capillary sample results are correctly identified as capillary on both the RAPIDPoint 500e system display and the instrument printouts. The issue only affects the new software version 5.3 and only capillary sample mode is impacted. The inability to distinguish specimen sources for blood gas may lead to incorrect diagnoses and management decisions.

A firmware error may lead to an incorrect association of test result(s) to a sample ID and therefore to an incorrect patient result. The mis-association of test results, or a delay in testing, may occur when all the conditions listed below occur within a few milliseconds timeframe of each other: - The SRM module is releasing a sample tube (Tube A) just placed into the carrier - Another sample tube (Tube B) is erroneously not diverted into the SRM module buffer - There is divert gate malfunction and a narrow timing window Only in this specific scenario, Tube A may be released by the module as Tube B due to a miscommunication between the module firmware and the Automation software without a unique error message being generated. The Automation System loses the traceability of Tube A. It manages both Tube A (incorrectly identified as Tube B) and the real Tube B according to the pending test orders (not yet performed) on Tube B.
